Tool! whom 'it 'may concern:

Be it known that I, LEE XVI-irriteren, a citizen of the United States, residing at Latti more, in the county of Cleveland and State of North Carolina, have invented certain new and useful Improvements in Vehicle of which the following is a speciiication.

This invention relates to the class of carriages and wagons, and vehicle brakes and has for an object to provide a brake which will beautomatic in action and which will be effectively applied to the rear wheels of a vehicle during its travel down grade.

Other objects and advantages will `be apparent from the following description and it .vill be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the eral. views', Figure 1 is a side elevational view of a vehicle showing the application of the present invention thereto, Fig. 2 is a bottom plan view, `Ti`ig. 3 is a longitudinal sectional View through the draft pole showing the manner of attaching a brake rod thereto. Fig, 4 is a transverse sectional View through the brake beam. Fig. 5 is a detail vertical sectional view on the line 5-5 of Fig. l.

Referring now more drawings, there is shown a vehicle consisting of the usual front and rear axles l0 and 11 res eetively provided with ground wheels of or inar construction, and these axles are connected y a center pole 13. The rear axle is provided with the usual bolster 14. as shown, and this bolster and axle respectively receive the innerends of hounds .l5 connected at their forward ends by a metallic slate 16 to the center pole as shown at 17.

he front axle is provided with similar hounds 1.8 which carry at their forward ends a draft pole 19.

The center pole is provided with a transversely extending beam 20 located slightly in advance of the forward edges of the rear wheels of the vehicle, and this beam is grooved upon its upper edge as shown at 21 and thus receives. a transversely. extending rod 22. The rod 22 is provided with dependparticularly to the more particularly to l ward end thereof.

brake beam are provided with shoes 27 for engagement with the rear wheels of the vehicle as will be hereinafter set forth. The rod 2l is secured to the beam 20 by means of staples or similar fastening devices28 and it will thus be seen that the rod 22 is mounted for rocking movement to bring its .brake beam toward and away from the rear wheels of the vehicle.

The hounds 15 'are provided with brackets 29, and these brackets are provided with depending portions 30 which are .connected by a horizontallydisposed portion 31 which is'thus arranged in spaced relation to the hounds; rlhe portion 31 is providedwith a longitudinally extending slot 32, and these brackets are thus arranged to receive links 33 and 34 respectively pivoted between the walls of the slots as shown at The links, at their centers, are each provided with a plurality of vertical passages 36 whereby the links are adjustably connected. V

At their inner ends, the links are provided with velongated slots 37 which receive a vertically disposed pin 38 carried by the leg members 39 of the forked end vof a rod 4() which is slidable in brackets beneath the pole 13, and this rod is connected at its front end to a brake rod 41 slidable in a bracket 42 depending from the draft pole.

The rod 41 at its forward end is pivotally connected to a member 43 which is pivotally connected to the pole. 19 at the forvided` with a plurality of adjusting openings 44, and at the upper end this member is provided with a neckyoke 45. The rod 41 rearwardly of the member 43 is provided with a rack bar 4G having a plurality of transversely extending .rack teeth 47 arranged to receive the lower end of a pivoted stop 48 carried by the draft pole 19.

The links 83 and 34 respectively at their outer ends are provided with a series dof adjusting openings 49 arranged to receive the rear ends of rods 50 pivotally connected at their forward ends to the brake beam 25, as shown.

It will thusbe seen that u of the Yvehicle d own grade,

on movement t at the horses The member 43 is pro- HJtions of the rod,

or draft animals in their tendency to hold back the load will-carry the neckyoke in a' rearward direction, thus operating the brakev rods as is obvious, which, in turn, will control the links 33 and 34 respectively to effectively apply the brake shoes to the rear wheels of the vehicle. The provision of the stop which is engagedlat its lower end with the teeth of the brake rod is such that the brake shoes are held disengaged from the wheels during backing of the vehicle until the stop has been released, which may be conveniently effected by the foot vof the driver.

What is claimed is: l. The combination with a vehicle including rearward hounds, of depending brackets carried by lthe hounds, a center pole located between the hounds, a transverse member secured upon the hounds and upon the center pole, a'rod mounted upon the transverse member for rocking movement, said rod having depending end portions, a brake beam secured to theA depending end porbrake shoes carried by the brake beam, a normally transversely extending link pivoted in each bracket, a rod pivoted to the outer end of each link, said rods being pivotally connected with the brake l beam, said links being provided with longitudinal slots at their inner portions and being overlapped, a pin slidably engaged in the slots, a rod having a forked end pivotally engaged with -the pin, said rod extending forwardly, a depending bracket carried by the draft pole, a rod pivoted at its rear end to the forward end of the first. named rod, said second named, rod extending i through the bracketrand having upwardly directed rack teeth, a ,pivoted stop carried by the draft pole and arranged for engagement with the rac-k teeth to hold the second named rod at different points of its movement, a member pivoted formovement in a vertical 'plane to the forward end of the draft pole, and a neck yoke pivotally conber, said second named rod being pivotally connected with the lower portion of the said member.

2. The combination with a vehicle including a draft pole, front and rear axles con nected with the center pole, wheels carried by the axles and rearwardly divergent hounds connected with the center pole at their forward ends and with the rear axle at their rearward portion, of depending brackets secured to the hounds, a normally transversely extending link pivoted atkeach bracket for movement iny a horizontal plane, said links being overlapped at their inner portions and having registering longitudinal slots, a longitudinally extending rod slidable connected with the center pole, and having a forked rearward end disposed with its spaced portions above and below the overlapping portions of the links, a pin engaged in said spaced portions and in the slots of the links, a brake beam pivotally connected with the rearward nounds and with the center pole for movement toward and away from the rear wheels, brakel shoes carried by the brake beam and arranged for engagement of the rear wheels, rods pivotally connected with the brake beam and with the outer end portions of the links, a vertically extending pivoted member carried by the forward portion of thedraft pole, said pivoted member extending above and below the draft pole, a rod pivotally connected with the first named longitudinally extending rod and with the lower portion of the pivoted member, and means for holding the second named rod at differentv points of its longitudinal movement, said vertical member being arranged for attach nient of the neck yoke to its upper portion.

In testimony whereof I affix my signature, in'presence of two witnesses.
